Can I just say as a newbie to this forum. When there is a little contest on the road between cars, you may find that it is not the cars capabalitlies or horsepower that wins, rather then the driving skill and the drivers knowledge of his/her own cars capabilities.
You can get a yob in an a5 and he can drive really fast in a straight line. When the bends come and you watch him brake through them just shows.
Not everyone can read bends at high speed, watching the vanishing point, knowing whether to keep the power on as it is or accelrate out of it coz the vanishing point of the bend is opening up.
It is not the car, it is the person behind the wheel, even if you know the roads, knowing how to read bends helps!
Sorry just rambling on!
